Application filed January 15,

To 'aZZ whom it may concern:

Be it known that 1, JAMES PARK, a citizen of the United States, residing at Hopkins,

.111 the county of Hennepin and State of Minnesota, have invented a new and useful Tile, of which the following is a specification.

This invention relates to a tile formed of burned clay or like material and which is especially designed for use in the construction of sewers and other conduits.

One of the objects of the invention is-to provide a tile which, when sold to the t ade, is made up of two opposed integral segments adapted to be broken apart after which they can. be reassembled end to end and held together by a suitable binder.

A further object is to provide a tile'so constructed as to be capable of resisting strains inwardly in all directions and the sides and ends of which are so shaped as to interfit so that when a binding mediinn is employed, a strong and watertight joint is produced.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed,'without departing from the spirit of the in vention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is an end elevation of the block prior to the separation of the segments thereof.

Fig. 2- is a side view block shown in Fig. 1.

Fig. 3 is a perspective view segments of the block.

Fig. i is an end elevation showing blocks connected to form a portion of a conduit.

Fig. 5 is an end view of a portion of one course of segments and showing their ends interfitting.

Referring to the figures by characters of reference A and B designate oppositely disposed like segments connected by integral webs C extending throughout the length thereof. Each of the segments is bowed of a portion of the of one of the Specification. of Letters Patent.

together at their ends.

transversely and is provided with longitudinal radial webs or partitions 1 and parallel straight partitions 2, these straight partitions bein extended from one side to the other of tie segment and cooperating with the radial partitions 1 to divide the interior of the hollow segment into separate cells 3. Formed along one side of each segment are side ribs 4 and a central rib 5, the side ribs being located along the inner and outer edges respectively of the side. Formed along the other side of each segment are parallel ribs 6 so positioned that when two segments are positioned with their sides close together, the ribs 6 on one segment will project into the channels 7 formed between the ribs 4 and on the neXt adjoining segment.

The sides and the partitions 1 segment are cut away at one end to form a straight substantially semi-cylindrical chair nel or recess 8 extending from one side to the other of the segment. At the other end of said segment is provided a straight sub stantially semi-cylindrical tongue 9 of approximately the same proportions as the recess 8, the partitions 1 and 2 being eX- tended to form the tongue.

As before pointed out, the block consists of two opposed segments A and B connected by integral webs C. By thus connecting a pair of segments, the two parts can be compactly stored for shipping purposes and more rapidly handled than where the segments are formed in separate pieces. When it is desired to set up the segments the webs C are broken by means of a hammer, or the like so as to separate the segments whereupon one of the segments is reversed relative to the other and the tongues or ribs 6 thereon are inserted into the channels 7 of the other segments, a suitable binder being placed in the channels so as to cement the parts together. After a desired number of segments have been assembled to produce a conduit of the desired diameter, the conduit can be lengthened by erecting additional segments so that the tongues 9 on one set of segments will project into the grooves 8, on the next adjoining set of segments, a suitable binder being placed in the grooves 8 for the purpose of cementing the segments The radial ribs 1 will obviously reinforce the segments against inward strains and the partitions 2 will likewise reinforce the segments against and 2 of the lateral strains. By having the ribs and tongues arranged in the manner shown it will be obvious that when the various segments are assembled and cemented together, Waterproof joints Will be provided. The segments can be used in erecting conduits of different diameters Without necessitating any change in the size or shape of the segments.

By having certain of the cells extend into thevtongues 9, spaces are provided for the reception of portions of the binder used in securing the ends of the segments together so that a very tight joint is thus provided. The cells above and below the tongues 9 will also receive portions of the binder.

hat is claimed is A conduit segment, comprising transversely curved inner and outer Walls, spaced Copies of this patent may be obtained for five cents each, by addressing the parallel straight walls lying between, and spaced from the inner and outer Walls, ra' dial partition Walls connecting the before mentioned Walls, there being a groove at one end of the segment and extending trans vcrsely thereof, a tongue arranged trans rersely of the other end of the segment, straight parallel. ribs along one side of the segment defining channels, and ribs on the other side of the segment spaced to corre spend with the channels. v r

In testimony that I claim the foregoing as my own I have hereto ailixed my signature in the presence of two Witnesses.
